/* This example demonstrates the usage of physics faces.
 *
 * Faces references other groups of the collection. The same group
 * can be used for many faces, but to illustrate it we are adding
 * a rectangle of different color for each face of a cube.
 * It will apply impulses on the cube when receiving messages, so
 * it's possible to see the cube rotating and moving.
 *
 * It can be tested with edje_player slave mode
 * $ edje_player -S -p -g example_group physics_3d.edj
 *
 * message 1 FLOAT_SET 3 80 -100 0 -> apply an impulse on red box with
 *    x = 50, y = -100, z = 0, for example
 * message 2 FLOAT_SET 3 0 100 0 -> apply a torque impulse on red box with
 *    x = 4, y = 0, z = 0.8, for example
